Spawn Actor from Class collision check problem

So I made a quick video to show exactly what I’m doing here, as the photos of the blueprint were cumbersome.

In essence.
The blueprint level spawner will make an asteroid field.
The asteroids are various scales, and have collision volumes etc all sorted out.
However, the spawn even if colliding option doesn’t seem to check for objects as the asteroids continue to spawn touching each other.
The level spawns everything inside a big sphere and I followed a similar guide to the one that spawns cows from youtube (toy cows, that is).

Anyway, thoughts would be appreciated.
